Product specification
Micro computer for moisture measurement
Description
NECON 21 is a processor-controlled micro computer for calculating the moisture in bulk goods and solids in combination with a neutron radiation source and the corresponding detector.
By choosing a suitable detector for 2π or 4π geometry, the device can be optimized for the measurement task.
The calibration provides a moisture value in percent [%]. The internal calibration table stores up to 20 reference values.
All inputs and outputs are floating and protected against reverse polarity. The humidity value is also available as a current signal (0 / 4-20mA) with 10 bit accuracy (better than 0.5%).
The scaling of the output current can be freely defined.
In addition to the microwave measuring section, a distance measurement with ultrasound is used as a "light barrier"
The raw data of the microwave sensor measuring section are processed by the evaluation computer; the measurement result is the percentage moisture in the measured material.
The measured value can be transmitted to other evaluation devices via an analog current output (0 / 4-20mA).
